We have over 30 years experience in the operation of a nitric acid based chemical brightening process. It is normally used as a pre-treatment (to anodising) to achieve a bright reflective finish on parts that are to be used in a highly decorative application – subsequent anodising preserves and protects the bright finish.
To obtain the very best finish, parts should be mechanically polished first to remove any scratches or other surface blemishes.
Please note (as a result of their chemical make-up) not all aluminium alloys are ideally suited to chemical brightening. If you require any advice on this subject, feel free to discuss your needs with us.
